Device and method for the administration of a substance

1. An aerosol spray device, comprising a spray bottle containing a substance and having an actuator engaged therewith and configured for releasing the substance from the spray bottle, the actuator extending from the spray bottle along a first axis, the actuator further including a tubular member extending therefrom along a longitudinal axis and defining a first channel extending along the longitudinal axis, the longitudinal axis being non-parallel to the first axis, and engaged with a dispensing head distally to the actuator, the dispensing head defining an axis parallel with the longitudinal axis of the tubular member and having a larger dimension transverse to the dispensing head axis than the tubular member transverse to the longitudinal axis, the dispensing head defining at least one orifice in communication with the first channel and configured to dispense therethrough an aerosol spray containing the substance released from the spray bottle, via the actuator and the first channel upon actuation of the actuator, at an angle of substantially 90±35 degrees with respect to the dispensing head axis, the dispensing head thereby being adapted to administer the substance to an oral cavity of a subject by directing the aerosol spray directly to an area in the front of the mandibular teeth of the subject, an area behind the teeth of the subject, or an area under the tongue of the subject.

2. The device according to claim 1 , wherein the substance has a disagreeable taste and/or is a source of irritation.

3. The device according to claim 1 , wherein the substance is selected from the group consisting of alkaloids, including nicotine, nicotine derivatives, nicotine salts, lobeline, lobeline derivatives and lobeline salts; meclozine diphenhydralamine and promethazin.

4. The device according to claim 1 , wherein the substance is nicotine.

5. The device according to claim 4 , wherein the nicotine is in the form of a free base.

6. The device according to claim 1 , wherein the orifices are evenly spread around a periphery of the dispensing head.

7. The device according to claim 1 , wherein the orifices are disposed in a lower part of the dispensing head.

8. A spray device including an actuator adapted to engage a source of a substance, the actuator being configured for releasing the substance from the source and extending from the source along a first axis, the actuator further having a tubular member extending therefrom along a longitudinal axis and defining a first channel extending along the longitudinal axis, the longitudinal axis being non-parallel to the first axis, and engaged with a dispensing head distally to the actuator, the dispensing head extending along the longitudinal axis and having a larger dimension than the tubular member transverse to the longitudinal axis, the dispensing head defining at least one orifice in communication with the first channel and adapted to dispense therethrough an aerosol spray containing the substance released from the source via the actuator and the first channel upon actuation of the actuator, the at least one orifice being configured with respect to the dispensing head such that the aerosol spray is dispensed at an angle of substantially 90±35 degrees with respect to the longitudinal axis of the tubular member, the dispensing head thereby being adapted to administer the aerosol spray containing the substance directly to an area in front of the mandibular teeth of a subject, an area just behind the teeth of the subject, or an area under the tongue of the subject.

9. A method for oral administration of a substance to a subject, comprising delivering an aerosol spray containing the substance to the front of the oral cavity of the subject, via a spray device including an actuator engaged with a source of the substance and extending from the source along a first axis, the actuator being further configured for releasing the substance from the source, the actuator having a tubular member extending therefrom along a longitudinal axis and defining a first channel extending along the longitudinal axis, the longitudinal axis being non-parallel to the first axis, and engaged with a dispensing head distally to the actuator, the dispensing head extending along the longitudinal axis and having a larger dimension than the tubular member transverse to the longitudinal axis, and the dispensing head defining at least one orifice in communication with the first channel, by directing the aerosol spray containing the substance released from the source, through the actuator and the first channel defined by the interposed tubular member, and through the at least one orifice upon actuation of the actuator such that the aerosol spray is dispensed at an angle of substantially 90±35 degrees with respect to the longitudinal axis of the tubular member to the front of the oral cavity of the subject during the delivery to substantially avoid deposition of the substance in the back of the mouth.

10. The method according to claim 9 , wherein the front of the oral cavity is an area in front of the mandibular teeth of the subject, an area just behind the teeth of the subject, or an area under the tongue of the subject.

11. The method according to claim 9 , wherein the substance has a disagreeable taste and/or is a source of irritation.

12. The method according to claim 11 , wherein the substance is selected from the group consisting of alkaloids, including nicotine, nicotine derivatives, nicotine salts, lobeline, lobeline derivatives and lobeline salts; meclozine diphenhydralamine and promethazin.

13. The method according to claim 11 , wherein the substance is nicotine.

14. The method according to claim 13 , wherein the nicotine is in the form of a free base.

15. A method for assisting in the reduction of the desire of a subject to use nicotine or nicotine containing compositions, comprising delivering an aerosol spray including a nicotine containing substance directly to an area in the front of the oral cavity of a subject from a spray device including an actuator engaged with a source of the nicotine containing substance and extending from the source along a first axis, the actuator being further configured for releasing the nicotine containing substance from the source, the actuator having a tubular member extending therefrom along a longitudinal axis and defining a first channel extending along the longitudinal axis, the longitudinal axis being non-parallel to the first axis, and engaged with a dispensing head distally to the actuator, the dispensing head extending along the longitudinal axis and having a larger dimension than the tubular member transverse to the longitudinal axis, and the dispensing head defining at least one orifice in communication with the first channel, by directing the aerosol spray including the nicotine containing substance released from the source, through the actuator and the first channel defined by the interposed tubular member, and through the at least one orifice upon actuation of the actuator such that the aerosol spray including the nicotine containing substance is dispensed at an angle of substantially 90±35 degrees with respect to the longitudinal axis of the tubular member to the front of the oral cavity of the subject during the delivery to substantially avoid deposition of the substance in the back of the mouth.

16. The method according to claim 15 , wherein the front of the oral cavity is an area in front of the mandibular teeth of the subject, an area just behind the teeth of the subject, or an area under the tongue of the subject.

17. The method according to claim 15 , wherein the nicotine containing aerosol spray contains nicotine in the form of a free base.
